Which of the following is not vegetative propagule?

Options

A. Rhizome and sucker
B. Tuber and offset
C. bulbil (e.g. in Agave), leaf buds, bulb
D. Antherozoid

Answer

To determine which of the following is not a vegetative propagule, we will analyze each option provided:

1. **Rhizome**:
- Definition: A rhizome is a horizontal underground stem that can produce new shoots and roots.
- Example: Ginger is a common example of a plant that reproduces through rhizomes.
- Conclusion: Rhizomes are vegetative propagules.

2. **Sugar**:
- Definition: This likely refers to "sugarcane," which can also propagate vegetatively through its stem cuttings.
- Example: Strawberries can reproduce through runners, which are also vegetative structures.
- Conclusion: Sugar (sugarcane) is a vegetative propagule.

3. **Tubers**:
- Definition: Tubers are swollen underground stems that store nutrients and can give rise to new plants.
- Example: Potatoes are a classic example of plants that reproduce through tubers.
- Conclusion: Tubers are vegetative propagules.

4. **Offsets**:
- Definition: Offsets are small daughter plants that develop from the base of the parent plant.
- Example: Water hyacinth produces offsets that can grow into new plants.
- Conclusion: Offsets are vegetative propagules.

5. **Anthrozoids**:
- Definition: Anthrozoids are male gametes (sperm) in certain plants and are involved in sexual reproduction.
- Conclusion: Anthrozoids are not vegetative propagules; they are sexual reproductive structures.

**Final Answer**: The option that is not a vegetative propagule is **Anthrozoids**.
